Title: Laser output controlling device
Inventor: OTANI AKIHIRO
IPC: B23K26/00
Filed: 1987-11-18
Abstract: PURPOSE:To prevent an optical characteristic of a laser output from being lowered even with an increase in an oscillated laser output by a method wherein a reflected beam of a beam splitter is taken out as the laser output and a transmitted beam of the beam splitter is used as a monitor beam to be detected by using a photodetector. CONSTITUTION:A laser beam P0 which has been output from a CO2 laser oscillator is split by using a beam splitter 5; one split laser beam P1 is taken out as a laser output; the other laser beam P2 is incident on a photodetector 6 and is used as a monitor input; an output of the laser oscillator is controlled in accordance with the monitor input. In this laser output control device, the laser beam P1 taken out as the laser output is used as a reflected beam of said beam splitter 5. By this setup, because an output of a monitor beam is small as compared with the laser output, the possibility that the beam splitter is heated and that an optical distortion is caused is eliminated; it is possible to always obtain the laser output whose beam quality is excellent.

Title: Illuminator
Inventor: MAKIHATA AKIRA
IPC: G09F9/00
Filed: 1991-11-06
Abstract: PURPOSE:To enable controlling light up to a low brightness level without being affected by ambient temperature by sensing light emitted by a fluorescent lamp and feeding it back to a dimming circuit. CONSTITUTION:A photodiode, a phototransistor, or CdS, etc., are used as an optical sensor element 5 whose output is amplified by an amplifier 6, smoothed by an integration circuit 7 and then adjusted by a variable resistor 8 to a proper-level voltage VP. The voltage Vp is proportional to the brightness level of the fluorescent lamp and a differential amplifier 9 compares the voltage Vp with a fluorescent lamp dimming designation level voltage Vb. The output voltage V1 of the differential amplifier 9 is K(Vb-Vp), where K is the degree of differential amplification; and an addition computing element 10 adds the Vb to the V1 and its output voltage V0 is V1+Vb and used to control the dimming circuit. Consequently, the brightness of the fluorescent lamp is prevented from varying with the ambient temperature and the light can be controlled even to the low brightness level without turning OFF the fluorescent lamp.

Abstract: PURPOSE:To prevent the deterioration of a device by means of an excess voltage at the time of burn-in testing by making a clamp level variable and lowering the clamp level at the time of burn-in testing lower than at the time of a normal operation. CONSTITUTION:A power source voltage drop means 130 receives an external power source voltage extVcc from an external power source voltage node 110 and outputs an internal power source voltage IntVcc which is obtained by dropping the external voltage to an internal power source voltage node 140. A boosting means 150 is driven by receiving the voltage intVcc from the node 140 and gives the voltage which is higher than the sum of the internal power source voltage intVcc and the threshold value voltage of an n-channel MOS transistor 161 to an internal circuit 160 through a boosting line 170. In this configuration, the clamp level of a clamping means 180 is changed by a clamp control signal/phic1 from a clamp control means 190. Therefore, the clamp level at the time of burn-in testing can be made lower than the clamp level at the time of the normal operation.

Filed: 1987-11-17
Abstract: PURPOSE: To perform cooling to a desired temperature in an early stage without generating ice pieces inside a cooling coil by providing an agitator control means for intermittently driving an agitator. CONSTITUTION: Water near a cooler 16 is cooled by the cooler 16. Further, it is agitated by the agitator 13 and cooling is performed over the entire area of a water tank 17.

Abstract: PURPOSE:To obtain a device which can compensate the phase difference between a reference signal at a phase in the range from 0 to 2pi in a tracking receiver and an error signal without greatly affecting pass signal amplitude characteristics using a compact circuit. CONSTITUTION:An inverter 24 and a switch circuit 26 for inverting each signal phase are provided at the output of a clock signal generator 8 and that of a frequency divider 9, a switch is individually switched according to the control signal from the outside, clock signal and frequency divider output signal are set to inverted or non-inverted output, a switch for selecting error signal 0-pi/2 is switched by the frequency divider output signal, and then bi-phase PSK modulation is applied by the clock signal. Since 0-2pi variable phase shifter in a conventional example is changed to a 0-pi/2 variable phase shifter 28. the variable change can be reduced to 1/4 and hence the variable phase shifter can be miniaturized. Also, since the variable phase shifter variable range is narrow, the fluctuation in amplitude characteristics is reduced, thus stabilizing the detection sensitivity of Az and El error signals and maintaining directional accuracy of an antenna.

That is, on the one end side of the hollow yarn bundles 2, a fixing part 3A formed of the potting materials is arranged, and one end of each hollow yarn membrane 1 is opened at the end surface of the fixing part 3A. When forming the opening, the fixing part 3A is cut at a position of the chain line, allowing a fixing part 3C on the one end side to be removed and each hollow yarn membrane 1 to be opened at the cut surface of the fixing part 3A. At this time, before the fixing part 3C is formed, the hollow yarn bundles 2 are subjected to wetting treatment. In this way, the potting material is infiltrated into the formed position of the fixing part 3A to surely prevent the occurrence of pinholes in the fixing part 3A.
